hi guys!

i try to aswer some question :)

because im using a new freq step for the cpu, im recommended that check the setcpu (or similar) app profiles. if you are using some of the step what is not existed anymore that would be a problem.

who still have bsod try to raise the minimum cpu freq to 389mhz. it not eat noticable more battery but probably helping the stability.

the voltages what i used is calculated from the stock voltages. im not planning to change them, because many phone working different with the undervolt.

if you want, you can undervolt your phone but after its possible that you may have bsod, so be careful with the undervolt.

for who need a kernel only installer: tomorrow :)

hmm ty so much m8 but i did format cache and format dalvik cache too and when i reboot my phone its still stuck in LG screen logo and didnt boot up or anything just see that LG logo and the 4 button flashing thats all nothing else =( because i would like find out some damm cache and rom which i can playing games on phone because every damm games freezeng on first or second level or even after 5mins playing games always freeze and even i use camera for over 5 mins its freeze the phone and i cant do nothing just take off battery =((

please can any1 help me out with this freezing thing which ROM + kernel shall i use for can play on phone and can use it for over 5mins ? =(
[LG Optimus 2x] isd88:
i tried your last kernel, i like it and it don t seems to have any problem. just two question :

1) is there any way to disable bravia engine ?

2) which launcher does the smoothness fix help? i use go launcher and i m not able to understand if the improvement help my launcher

thank you!
[LG Optimus 2x] TheDaftandFilthyOne:
Seems rock solid and very smooth so far
[LG Optimus 2x] 75markus:
+1 !

3001 shared works fine till yesterday with no bsod !
[LG Optimus 2x] grognaz:
im gona try your tip with higher min clock and see if that works.

btw have you read about the bravia engine missing some stuff to make it really work? someone posted some info in the bravia thread about it and since you seem to have goos knowledge of how things work maybe you can take a look at it?
[LG Optimus 2x] pastime1971:

The new Kernel is realy good and runs perfectly smooth, but with the 32 MB Ramhack shared version that I use I´am getting a BSOD after 30 seconds listening music.

Has someone else this bug?
[LG Optimus 2x] mind_challenge:
I have no such problems, tried with stock player, and poweramp.
[LG Optimus 2x] ergoen:
I had a similar problem a few days ago when listening to music with spotify, I wasn't sure if it was the rom or the kernel though. (Currently using stock cm7kernel with temasek's latest without that issue, so it might have been the kernel, I was also using the 32 shared version.)
[LG Optimus 2x] vadonka:
like i said before the shared version may be have some "unknown" issues. try the standard 32m ramhack version instead of the shared.
[LG Optimus 2x] Buccio:
hi guys and hi vadonka... your kernel is very very great and i use it since the first release without any problem.. my question is, the last version codenamed "etana" has the 32bpp/24bpp mod?? :)
[LG Optimus 2x] plakers:
Does the kernel supports "governors" selection (saw the schedulers' choice in tweakio script) - I mean, will a "powersave" or "performance" be available instead of the hardware one?

(would like to optimize my battery life, which is 15hours, with 8 idling... poor)

Any alternative to get them as modules?

Any impact of schedulers (cfq, bfq...) on battery life?
[LG Optimus 2x] jacobmllr95:
But what are the main differences between the shared and the normal 32 MB Ramhack version? With the shared, reboot works. But with the normal version not...
[LG Optimus 2x] withoutwings:
No, discussion a few pages back deemed those mods unnecessary.

Sent from my Optimus 2X
[LG Optimus 2x] withoutwings:
Shared is a "use at your own risk" version, so any problems then switch to another.

It allows the CPU and GPU to share a memory region, which has the potential to be problematic but works ok for some (myself included).

[LG Optimus 2x] annashaman:
hmm oky ty i try it in a min, im using CM7 Kang 204-52 and i dont use any kernel because when i install kernel any of them when i turn on or reset my phone its always stuck in LG logo and dont go boot up, and if i install back CM7 kang rom its boot up but never worked with kernels =(
[LG Optimus 2x] grognaz:
@vadonka: i set the min freq to 398mhz and did not have an other SOD so far. guess in my case it really is the 218mhz which makes the problems.

do you think its just a voltage problem or might there be an other problem at that freq?
[LG Optimus 2x] annashaman:
hmm m88 i installed it really cleared everything even SD card formated cash dalvic etc but when i installed your ROM its do the same when i install kernel its stuck in LG logo but why ??? whats wrong with my phone ? :( i use 405 based and 405 ril i think
[LG Optimus 2x] vadonka:
or even both, thats why im redefined the freq table. 389mhz its seems to be stable in every phone but 216mhz not. no matter if you set the voltage even 800mV, in 216mhz have bsod. its probably related to the hardware.
[LG Optimus 2x] grognaz:
but why was it working on stock cm kernel or on your early kernels?

and isnt the 216mhz a stock freq?
[LG Optimus 2x] vadonka:
because im using an older cpufreq driver and different voltages. the older cpufreq driver is incompatible with many phones..

the current version is working for almost everyone. thats my top goal :)

because that this phone have many different hardware type its hard to find such a configuration what is good for everyone.
[LG Optimus 2x] fuxmen:
Is there any chance to improve battery life with data on? My phone with always WiFi on is rock, battery life is very good. But only when WiFi switch to data i am talking about 2g the battery graph starts to going down faster. On 3g its not even acceptable :-(

I have high end phone and can't even work with 3g/HSDPA because off massive battery drain :-(
[LG Optimus 2x] Craxx:
I use tasker to disable data when screen is off and enable when screen is unlocked:)

Craxx;)

[LG Optimus 2x] Shadowman19:
That is true, left the phone with display and wifi on after a full charge and lost only 20 percent in two hours, which is awsome. Then I used it in the bus with 3g and lost 1percent every 2-3 mins... that is - even compared to my girlfriends galaxy s - horrible. Isnt there amything one could do? Thanks
[LG Optimus 2x] montresor60:
Just wondering; is the Galaxy S set to 2G or 3G? 1 per cent drain every 2-3 minutes on 3G seems 'normal' for the 2X, regardless of ROM or kernel.

Using Tasker to enable / disable data based on screen state is a good idea but I don't necessarily want or need data when the screen is on.

My solution: use 2G unless downloading large files or streaming video. This is easily managed with the Widgetsoid 2G/3G switcher widget. One tap and it calls the 'mobile settings' dialog where I can enable or disable data (disabled by default). One more tap in the same dialog to select 2G or 3G. Works very well for me.
[LG Optimus 2x] plakers:
no bsod at all with all versions (currently using @ -25 undervolt to all freq) and I've got a SetCPU profile that limits freq to 216-389 on screen off

please do not raise the voltage too high ;)

I'm not sure that it is freq/volt related, because older versions were a bit lower in voltage, and same frequencies, and the bsod didn't occurs. could be a hardware/module problem?

battery life : i went from 725 to 824, then 218, and now 622... seems that the 218 one with 606RIL were the best for me, with good sound quality and signal stability, give you another feedback soon!

schedulers/governors : is it planned to implement some other governors than the hardware ones (ported from somewhere else?) - what is the impact of scheduler on battery/performance? (cfq? bfq? sio?...)

Thanks! ;)

Tasker for me : set my phone to use 2G only, except while launching some specific apps (market, browser...) => switch to 3G, but the delay forces me to reload the first requests - an alternate solution for me, even if it's not so efficient, it's mine for the moment...
[LG Optimus 2x] fuxmen:
Now i have turned off data because in work and home have wifi, but i want data on always because i use communicators, go chat etc... It is horrible that that kind of phone cant handle 2g data all the time without effecting battery. On my OLD Nokia e51 have always on data or always off it bearly make a diffrence, I miss that :(
[LG Optimus 2x] montresor60:
I have to wonder if it's not because of the sloppy coding of those communicator apps. I've given up on Viber, Skype and those kinds of things running in the background all the time. They just chew resources and slow everything down while killing the battery.

Again; maybe it's because of the more efficient, embedded apps. I sometimes miss my old Palm Treo 650, although my wife uses it quite happily and sees absolutely no need to step up to a 'Smart Phone'. She's on that thing all day and the battery goes for days on one charge. Her prepaid phone plan has a 500 MB / month data allowance and she doesn't use any of it. No Facebook or Tweeting for her; just good, old-fashioned SMS.

I've notice one issue when a use phone for games and it became a little hot deiffrent tools show a temp. around 40-42 degree. When I connet it to AC charger and screen is off after fiev seconds phone have BSOD or is off ... it doesn't happen when charching on USB I must test it. I tried 2 krenels IronKrnel and ETaNa :).

Sorry for poor english ... writing on PC ... phone has dictionary and autocorrect :P
[LG Optimus 2x] fuxmen:
I use the same apps that I use on Galaxy3 and on G3 batt life was way more better :(
[LG Optimus 2x] vadonka:
i will remove the RIL tweak from the build.prop in the next release. it seems somehow also responsive for the battery drain while the phone in 3G.

i noticed that too, if the RIL tweaks are all disabled and using a 3G network the battery drain is noticable smaller.

however the 3G is still drain the battery fast, its normal. removing the RIL tweaks helps a little :)

the 3G network operation is highly depend on the baseband/ril. maybe an another baseband working better.
[LG Optimus 2x] fuxmen:
IMO slower 2g/3g is better then all that battery drain ;/ I use it mostly for sync, gtalk, weather check soo no need super speed tweaks or so. Just less battery drain
[LG Optimus 2x] vadonka:
i think so too :)
[LG Optimus 2x] fuxmen:
It's good that you agree with me :-) maybe in next version will be less battery hungry :-)
[LG Optimus 2x] tonyp:
1% per 2-3min is normal?! With 2,5min per % you would loose 24% an hour - so the phone would be dead in about 4 hours. To have my battery die in 4 hours I need to play games..
[LG Optimus 2x] maini85:
Absolutely! Current battery drain on 3g is really horrible.

@vadonka: Can we remove the tweak easily by ourselves till next release?
[LG Optimus 2x] 4lph4:
It's only a feeling, but it seems to me the battery drain has increased from the jan27 version.

The positive point is that is perfectly stable :D except for the radio part.

Today I had my first :( GSM signal lost with RIL218 and bb725. Never happened with previous versions.

Vadonka, do you think it could be connected with some new code merged from the LG sources?

In any case I changed the RIL to match the 725, let's see what happen.
[LG Optimus 2x] fuxmen:
try to turn 3g then start download movie (700mb) and waching YT in the same time, 2-3hmax I quarantee. when Im doing nothing just turn data on and 3g I lost % in 5-10min ;(
[LG Optimus 2x] rlees85:
anyone else noticed this? is there a way to get it back?
[LG Optimus 2x] vadonka:
hello guys

i found the major problem about the battery drain. its the second core management.

in the jan30 release im using a new cpu freq step. after 503mhz the next is 800mhz.

however i forgot to change the cpu1 activation threshold. its remain in 655mhz

but the phone never use this freq because its not existed anymore, so the cpu1 activation is not so good, activated too frequently.

3g is using more cpu time, so the phone running in higher cpu freq. probably not the 3g but the cpu management causing the battery drain.

if the cpu max freq set to 503mhz then use 3g, then the battery drain is much more lesser, so it must be the problem.

its just a small modification but seems to be important, so tomorrow i will fix this and release a new version. the ril tweak also help to save battery, so im removing that too.

sorry for that issue, my bad :)

at least the kernel seems to be stable, so it need just a few bugfix.
[LG Optimus 2x] rlees85:
I don't have a clue what I'm talking about so forgive me if I'm talking crap, but would it be an idea to re-introduce 655Mhz? Just seems 503->800 is a big jump, and again from 800->(1050/1100)?
[LG Optimus 2x] vadonka:
the problem is that only 8 slot available. but im think again...
[LG Optimus 2x] rlees85:
Sure... tbh you know whats best. This kernel has already stopped my phone freezing after calls, freezing randomly after a few days and also stopped the alarm from failing... so its great for me already! ;)

[LG Optimus 2x] isd88:
on my old optimus 3d central slots were not so used, more then 80% of the time was spent on upper and bottomer ones. i think could be a good idea to try an exponential or quadratic curve to preserve battery.

note that it stays quite a long time at LG logo after a flash.. I haven't really timed it, but I figure it should be around 2minutes.
[LG Optimus 2x] sauliux:
Ok, that's my 2 cents after using %signature%.

1. No way to change/edit min/max CPU freq.

2. On first charge battery drained very fast using 3G. From second charge - got almost normal as it was previous.

3. First day got couple of boot/loops(black screen flashing and trying to load launcher ,but just first day , so might be one of restored apps was doing so). Later did't repeat.

4. BB 824 and RIL v21f (European) does not see wifi channels above 11, so it's not European BB then or what... Call quality and data link - works without problems.

hope this will solve my poor problems ;)

as the voltages are a bit lower, to test in stable conditions my setup is :

- 216, 456 : no undervolt

- 608 and above : -25mV

went from setcpu to pimpmycpu, see if any change occur, and give my feedback soon (still on the 622 BB/RIL... some light battery drain related to it I think)

thanks again vadonka for this new job done :)
[LG Optimus 2x] vadonka:
i just find out now that the cm7 team merge more v20l updates. i already have most of them but there is a few missing. im merging this updates from the cm7 and test it. most of them not affect the kernel main operations, so its just a small updates compared to the current version.

this means probably a new version tomorrow :)

...If nature is kind to me, a massive blizzard is approximate to my country, the weather forecast says the expected snowfall is around half meter.

its been also very cold here, below -20 celsius degrees

i hope that the internet connection is stay alive in these circumstances

update: i noticed that the battery life is better with this latest version.
[LG Optimus 2x] plakers:
hehe -8°C here! but windy! my battery Temp. has gone down, no more problems with that for these days lol

downloaded, compared with v20l, almost identical...

the lg did not force himself..

diff patch file from comparing the v20l and the v20q: v20l_v20q_diff.patch

noticable difference:

Add ramzswap support and enabled by default (we have already the much better zram driver)

Add LZO compress decompress support (really needed? update: the ramzswap need the lzo compression too, so its needed :) )

Add some patch for the IO includes

Add support Tegra2 APB bus clock (it maybe usefull)

Wifi(bcm4329) use the andrey new dhd thread controls (not every hardware like this)

Add headset wake lock timeout support (it maybe usefull)

Battery charger disable power notification during FOTA upgrade (we dont need this because we dont use FOTA)

Remove GPIO Sleep status from the backlight driver and lowered the ALC voltages (mmm, its interesting)

MUIC disable MUIC interrupt during FOTA upgrade (we dont need this because we dont use FOTA)

Some other small patch, but nothing special

No upgrade in the tegra files and just a few in the star drivers. Im a little bit disappointed.

Used SetCPU for a while, but since few weeks, I try to maximize my batterylife, I don't know how often SetCPU and Pimp "polls" the state of the phone (idling, screenoff & so on...) : so I installed Pimp to see if it makes any difference - I also had some problems with SetCPU that didn't load the good profiles at a time/state, or the CPU clock was sometimes not as it was fixed in SetCPU

=>> You will pay on the market for the App, the APK is free of charge and gives the same options/functions

=>> But, you can support the developper(s) by buying their software/projects! Your choice/possibilities ;)

(I know, it won't be significant! lol)

You have to D/L the latest version of Pimp my Cpu (see the thread on xda) you can get there the APK and download for installation. With this version, some predefined profiles are already defined like :

- screenoff

- phone charging

- battery below a certain level

and for each, you can choose the I/O scheduler, the voltages and frequencies - there's also a "govenor" choice (powersave/performance) but it's "software based" I didn't see any difference and I think that the hardware one is the only one used in whatever situation.

I've got now 4 profiles:

Charged battery - Default

Cpu: 216/1100 mhz

ScreenOFF - Screen off

Cpu: 389/389 mhz

i also undervolt like that

1100 mhz -75mV

1015 mhz -75mV

800 mhz -50mV

503 mhz -50mV

389 mhz -25mV

216 mhz -25mV

[LG Optimus 2x] plakers:
Yep, freqency table in the last version is :

216, 456, 608, 800, 1015, 1100, 1216, 1408

You may need to delete en re-create profiles (or uninstall/reinstall PimpMyCpu)

I had the problem when the freq.table has changed

May be another way to force the "re-read" of the table, but I don't know how.
